Flatscreen between speakers

Has anyone found a solution to cancel or at least improve the acoustic glare caused by a flatscreen tv on the wall behind the speakers? I don’t have a dedicated room and have to share the room with my home theater setup. I have thought of using an appropriate curtain and treat the tv as if it was a window. I am also considering light 3D printed panels that I can temporarily hung when listening to music and take down when watching TV with the wife. 
I tried hanging a couple of thick towels on it to see if there would be any improvement and the answer is yes. The center image is more solid and a little deeper. Nothing drastic but if I could squeeze anything positive, why not. Please let me know if you have confronted this issue in the past and whether you were able to solve it. Thanks.

I had this exact problem for years (dual use hifi and home theatre) and it can be overcome without room treatment or tv covers.

Proper speaker positioning. I use Ron’s LOTS method - he has a video on YouTube. Once dialed in the difference between an open and holographic soundstage and something bland was as little as 1cm in positioning.

Funny thing, I once got my speakers setup perfectly, then 6 months later upgraded the tv from a 55” curved to a 65” flat panel. This single change was enough to destroy all that work and the glorious soundstage I had.

But it shows how critical the speaker positioning was to overcoming the centre reflection issue.

I  also had a tv cover custom sown and tried it after optimising with the LOTS method. It actually made things worse, because the positioning had already been done to account for the tv reflection. That’s also why changing to a different tv size had such an effect.
